Cliff Harris and Charley Waters were mediocre safeties who benefited from a great the Dallas front seven.
Rayfield Wright is the only one on your list who could be considered "great."
Jordan, Howley, and Hayes were merely "good."
They got burned by Stallworth in SB XIII.
Actually, Herb Adderly, Mike Ditka, and Lance Alworth are all in the Hall of Fame. Adderly won one Super Bowl with the Cowboys, and Ditka and Alworth won their only Super Bowl player rings as members of the Cowboys.
There will be more Cowboys in the hall. Aikman and Smith will go in on first ballot. If Irvin doesn't, it will be because of off-field problems. Charles Hailey should also go in, along with several members of the early ninties offensive line.
